OMG! Were you spying on me again? You know it is really weird peeping in on your own sister, right? I will make a deal with you though. I'm gonna sit on your face for a 20 count in my hot sweaty yoga pants. If you DON'Tpassout, then I will let you jerk off & cum all over my naked ass. I might even finger my tight asshole for you while you're stroking your cock. It's too bad for you that you will never really get to fuck me since you are my brother. Ha
